UNITED STA'rEs PATENT @Enron IMPROVEMENT IN COUPLINGS FOR ROPE-BANDS.

Specication forming part of Letters Patent No. 126,918, dated May 21,1872.

To all whom may it concern:

Be it known that I, HENRY BADCOCK, of Pittsburg, in the `county ofAllegheny and State of Pennsylvania, have invented a cernew and usefulImprovement in Band-Rope Coupling and I do hereby declare that thefollowing is a full, clear, and eXact description thereof', referencebeing had to the accompanyin g drawing and to the letters of referencemarked thereon.

The nature of my invention consists in providin g the band-rope of thedrivin g-pulley used in connection with machinery for manipulatin g thedrilling-tools, and other apparatus connected with the boring ofoil-\vells,'with a coupling consisting of a yoke, hook, and link,constructed, arranged, and operating with relation tO each other,substantially as hereinafter described.

To enable others skilled in the art to make and use my improvement, Iwill proceed to describe its construction and operation.

In the accompanying` drawing which forms part ot' this speciiication,Figure I is a side view Otmyimprovementin coupling for bandrope. Fig. 2is a face or front view Ot' the same. i

Arepresents the band-rope, one end of'which is attached to the yoke B,as indicated in Figs. 1 and 2, the other end being attached in likemanner to the end x ot' the link D. The hook C is provided with aT-head, e, which lits inbetween the bow of the yoke B at the pointmarked h. rIhe opening f Ot' the bow of the yoke B is of such size undform that the hook C may be uncoupled from the yoke by passing the T-head of the hook C out through the opening f, as indicated by the dottedlines in Fig. l, and by turning the end w of the link D up tO- Ward theyoke B, as indicated by the dotted curved line 1, the hook C may beentirely detached from the yoke B.

The operation of uncoupling will be readily comprehended by thoseskilled in the a'rt of manipulating the tools and apparatus connectA- edWith the boring of oil-wells without further suggestion by prolixdescription.

In the boring of oil-wells the driving and operating machinery isexposed to the weather, and it has been found by experience that theordinary leather belting at times, becoming wet by the dew and rainstretches, and is thereby rendered inoperative, and being exposedto theaction of the sun becomes crisped and cracked. These difficulties havecaused persons engaged in lthe boring of oil-wells to use what is knownasa sheave driving-wheel, frequently called the bull-wheel,77 andinstead Of the leather belting, they use a rope which is lessobjectionableas it is not so easily injured by the action Ot' the deWsand rains, Or the heat of the sun, the greatest difficulty being itsliability to stretch, requiring it to be shortened frequent-ly, bytaking a piece out Of the band-rope, which operation necessitatesseizing,77 or whipping the ends together with a cord, causing a loss oitime and labor.

The object ot' my improvement is to avoid these ditiiculties, which Iaccomplish by the use of a coupling, constructed as hereinbeforedescribed, which, when the band-rope becomes stretched, can readily beuncoupled, and, by twisting the rope, it can be shortened up so as tobring it to the required length, which Operation ot' uncoupling andtwisting Of the band-rope can be done with great facility and ease, andwith but little loss of time, which are great considerations with menengaged in the boring Of oil-Wells.

Having thus described the nature, construction, Operation, andadvantages `of my improvement, what I claim as my invention is- Thecombination ofthe yoke B, hook C, and link D with the band-rope A,constructed, arranged, and Operated with relation to each other,substantially as hereinbefore described,

and for the purpose set forth.

HENRY BADCOGK.
